It is mostly just audio, at this point, but I will probably be starting on video in the near future. Currently ported: libogg-1.1.2 libvorbis-1.1.0 flac-1.1.1 bladeenc-0.94.2 faac-1.24 oggenc I've poked around for a reasonable mp4 library in C and didn't find one, so I may write a native plan9 version. When I ripped and encoded my CD collection, I decided to use FLAC because it's lossless, so my music library is made up of whole CDs ripped and encoded in FLAC. As you can imagine, that's very cumbersome. I've been going through the process of splitting the albums into tracks, re-encoding them in ogg, and tagging the files. I have a (currently) rough rc script that does all of this automagically based on data from a cue sheet. I intend to add cddb/freedb support and parallelise it a bit such that you can give it a list of cpu servers and it will spread the encoding process across them. I also have plans for a streaming audio server akin to icecast or shoutcast. The nice part is it can probably be easily written as an rc script. I have quite a few other works-in-progress, but I don't really feel they're worth mentioning until I have more code.

MPlayer-1.0pre5 has it. I know this because I had to play around to see Vester's movie of Rob at Tokyo.☺ He must have used Mac to produce that mp4 movie. I tried first my T42, Oh! saddly it's going not the product of IBM, but someone in China. If I knew it before, I never bought T42! Anyway, I had thought WinXP must have everything what we can do on PC, however, that's MediaPlayer could not do it, then, I tried Linux, and either could not. Then, I tired the newest version of MPlayer, and then, I could see that Rob's movie on mt Linux box... Kenji ^ permalink raw reply [flat|nested] 10+ messages in thread

I checked it, too, and found two versions for free and product. And then, I avoided them. Next I tried Inter Video DVD(?) which works as a plugin for Windows Media Player. I chose it. This is because I'd like to be most lazy for WinXP, which means one soft for one kind of task.☺ Kenji ^ permalink raw reply [flat|nested] 10+ messages in thread

Actually, it doesn't. It can decode and parse an mp4 stream, but it cannot create or modify an mp4 container. The only libraries I've seen are libmp4v2 from mpeg4ip, which is what faac uses, and quicktime4linux, which while written in C is a really ugly interface. -- Christopher Nielsen "They who can give up essential liberty for temporary safety, deserve neither liberty nor safety." --Benjamin Franklin ^ permalink raw reply [flat|nested] 10+ messages in thread

I apologize in advance for omissions and misinterpretations. There was maybe a dozen or so people that attended the BoF, but we were fortunate to have lots of folks who have worked or are actively working on Plan 9. As far as new stuff, I think the most exciting piece was Ron's discussion (and demonstration) of his Xen Plan 9 port. Overall it seems much snappier than vmware and Ron is actively working to get the code released. In addition to the discussion and demo, there was some discussion on hypervisors, para-virtualization and why this is a good thing for Plan 9. I talked a bit about progress with v9fs (Linux support for 9P2000), and it seemed like the general consensus that this combined with Russ' plan9port applications are a really good thing. I also talked a bit about the stuff that I'm doing as part of my research - namely looking at using 9P to share resources between para-virtualized partitions. Ron Minnich talked a bit about 9grid along with talking about the status of DOE funding for 64-bit compilers and a 64-bit Opteron port. The short summary is there has been a bureaucratic snag with the funds - but hopefully it'll be straighted out real soon now and things can really get going. The general consensus on the 9grid stuff is it really needs someone to step up and kinda take ownership of doing some of the logistical overhead (setting up accounts, answering setup questions, etc.) Geoff told us a bit about 9netics and what they are working on. Sounds like he, Brucee, and Skip have found a way to be paid for working on Plan 9 stuff. As far as core Plan 9 progress goes - there seems to be a steady stream of patches and fixes going into the code. There are mechanisms to see what changes are going in on a day to day basis, but there is not always a good description of why the changes went in. I'm going to work on trying to come up with some sort of automated digest of the changes and post them to the plan9dev mailing list on a weekly basis. One of the biggest problem with the code at this point is that it has drifted out of sync with the documentation. If people are looking to help out, going over the documentation, man pages, and wiki and aligning them with reality would be a great service to the community. There was a little discussion on what happens when Lucent shuts off the lights. There seems to be a high level of confidence that all the vital pieces have been replicated by enough folks that we could have core community services (web, wiki, and more importantly sources) back up within a few days. We talked a bit about the FOAF/web-of-trust authentication model. And it seemed that folks thought that this was a bad idea.

My coding skills are sketchy at best and I don't have a ton of free time, but I would be more than willing to put in some time on the documentation, as long as someone else could follow behind me and ensure that I don't blaspheme or outright lie.
